Inside the Preferences pane, you can also tick boxes to automatically launch or connect the app when you boot your device. Anyone using the Windows or macOS app should tick the box to autoconnect “when joining insecure WiFi networks.” You can also tag individual Wi-Fi networks as trusted or untrusted, to make sure you’re always protected even if you forget to connect the app manually. These network rules—not offered on most apps, including IVPN’s mobile apps or any of TorGuard’s apps—will make sure you don’t forget your VPN when you need it the most.
There's a reason why all these VPNs are paid. Providing encryption and VPN services to millions of users is a resource-intensive work that requires servers across the world. A free VPN might be enough for something minor like checking foreign news occasionally. If you need a VPN on a regular basis, however, you’re better off with a reliable paid service.
Buffered VPN doesn't disclose much about the size of its network, but the 30-day money back guarantee means that you can take their service for a test drive and really get a feel for how well it performs for you. The company lost a few points from us because they do keep some connection information. They gained points for their client support, unlimited bandwidth, and generous number of simultaneous sessions allowed.
Ironically, in many cases, the faster your standard internet connection, the more speed you “lose” in percentage. Even if you have a 50 Mbps connection and this interconnection is poor, you probably won’t be able to make the best of the VPN service. For example, if you have a 5 Mbps connection, you’ll lose just 10-20% of bandwidth, but if you have 100 Mbps, connecting to a VPN may cause you to lose more than a half of your speed.

TorGuard also lacks extra features that are nice to have, like automatically connecting to the VPN when you’re on an unknown Wi-Fi network (which IVPN offers) or split-tunneling to choose which apps do and don’t route through the VPN (which ExpressVPN supports). And it offers no option to automatically connect to the fastest server, a feature our top pick lacks as well. But if you have above-average knowledge of networking, you’ll appreciate TorGuard’s more in-depth settings pane, which allows you to add scripts or kill specific processes when the VPN disconnects—neither our top pick nor popular services like Private Internet Access allow that kind of control.
GRE is sometimes used by ISPs to forward routing information within an ISP's network. To prevent the routing information from being forwarded to Internet backbone routers, ISPs filter out GRE traffic on the interfaces connected to the Internet backbone. As a result of this filtering, PPTP tunnels can be created using PPTP control messages, but tunneled PPTP data is not forwarded.
Cost - VPNs aren't too pricey, but they vary from vendor to vendor. If your main concern is price, then go with something inexpensive, or free - like Spotflux Premium VPN or AnchorFree HotSpot Shield Elite. By all means, try a free server but they do have a few drawbacks since they attract a lot of users. Free servers are often slower, and since most are ad-supported, they place adverts on the online pages you access. Others can even limit the speed of your connection, as well as your online time or amount of data transferred.
IPVanish is one of the few providers that owns and operates its own network of servers, rather than rents servers out from third parties. This guarantees customers a sturdy, uncongested connection and better privacy. The IPVanish apps include an auto-select feature that connects you to the fastest available server in a given country or city. You can monitor upload and download speed in real time. Traffic is protected by 256-bit AES encryption, and a zero logs policy ensures that no usage data is ever recorded. A single subscription allows users to connect up to five devices at once. IPVanish is particularly popular with Kodi users due to its fast speeds, great privacy features and because it is easy to install on most devices popular with Kodi users including the Amazon Fire Stick.
We tested each service using both the Netflix-operated Fast.com download speed test and the more comprehensive Internet Health Test; the latter measures speeds up and down through multiple interconnection points between Internet providers. We ran each test on the macOS version of each VPN software in its default configuration, with our test computer connected over Gigabit Ethernet to a cable modem with no other traffic running through it. We recorded baseline download rates without a VPN active of nearly 300 mbps, and we checked our non-VPN speeds at random intervals to ensure that our local ISP wasn’t affecting the tests.
The best VPNs offer a solid balance of features, server location, connectivity protocols, and price. Some are great for occasional use, others are geared towards getting around the location restrictions companies put on their apps and services, and others are targeted at people who do heavy downloading and want a little privacy while they do it. Here’s what you should look for.
There are several different VPN protocols, not all of which are used by all of the VPN services we reviewed. Most operating systems have built-in support for at least one of these protocols, which means you can use that protocol — and a willing VPN service — without client software. The full-fledged VPN services have online instructions for how to do this, as well as how to set up routers to connect directly to the services.
First and foremost, using a VPN prevents anyone on the same network access point (or anywhere else) from intercepting your web traffic in a man-in-the-middle attack. This is especially handy for travelers and for those using public Wi-Fi networks, such as web surfers at hotels, airports, and coffee shops. Someone on the same network, or the person in control of the network you're using, could conceivably intercept your information while you're connected.
